Eyewitness James told LBC 97.3's Iain Dale the incident has left him and his wife in shock.

"These two guys were crazy, they just were not there they were just animals," he explained.

"They
dragged the poor guy - he was obviously dead, there was no way a human
could take what they did to him. They dragged him from the pavement and
dumped his body in the middle of the road and left his body there."
